GM carbed intake manifold
#3
Making sure I got the correct intake manifold in. The GM part numbers have been ground down smooth. The guy said it was for an LS1/LS6, but the ports on the head side are square vs the cathedral style. Just checking to see if I got the correct manifold. He said it was GM part number 88958675, but mine has a threaded boss on one of the rear intake runners.

this intake is designed for carburators, and the absence of the injector roof area will never allow this intake for efi use without some machining.
a better example or comparison would be a fast against a efi vic jr.
but imo a fast vs a super vic with 90* elbow is a lot better matchup
